IUOE Local 25, 2604 S 4th St, Philadelphia, PA 19148, US

Our international "The Operative Plasterers and Cement Masons International Association, ( OP&CMIA ), was founded in 1864. The OP&CMIA then chartered local unions throughout the country. Our Local was chartered in 1916. We were a union of cement masons only. Our original territorial jurisdiction was the 5 county Philadelphia, Bucks, Delaware, Chester and Montgomery countries. In the early 1990's Local 592 merged with Local 94, Harrisburg, 107 York, 233 Allentown, 105 Reading and 100 Scranton/Wilkes-Barre to form Cement Masons & Plasterers Local 592 of Eastern Pennsylvania. In July of 1999 Local 699 of South Jersey, Delaware and Northern Maryland became part of the 592 family. Except for the plasterers of the 5 county Philadelphia area, which is Local 8, Our Local represents Cement Masons, Plasterers and shophands in eastern Pennsylvania. Since 1916 all the major concrete in this area was done by members of our local. Power plants and high rises, bridges and highways, sidewalks and curbs are all our legacy.
